Synthesis of volatile Cu(II) precursors containing beta-ketiminate ligands with bulky alkyl group

초록

Cu(II) complexes containing substituted β-ketoiminate ligand has been successfully synthesized by using a microwave with moderate yields. Reactions between CuCl2 and Na[OC(Me)CHC(Me)N(R)] in THF produced brown liquid, which resulted in Cu[OC(Me)CHC(Me)N(R)]2. Since the copper(II) complexes are paramagnetic, characterization of the complexes has been done by melting point, TGA, MS, and elemental analysis. Iso thermal TG curves have been obtained to check the volatility of the copper precursors and other properties of these compounds will be discussed.
